The International Monitoring System, an international network of seismographic sensors developed to verify compliance with the Comprehensive Test Ban Treaty, has agreed to release seismographic data that could be useful for Tsunami detection and early warning. However, the data release is on an experimental basis because there is still disagreement among the participants in the IMS as to whether the IMS should be providing early warning data.
Good overview of the status of the International Monitoring System, a global network of sensors in 89 countries that watch for nuclear tests and other seismic anamolies.
Parties to the Comprehensive Test Ban Treaty are expected to begin discussing next week whether to expand the responsibilities and capabilities of the treaty?s monitoring organization to include global tsunami alerts.
